Building a library is much like building a program. In this case, the
name of the primary is `LIBRARIES'. Libraries can be installed in
libdir
or pkglibdir
.
See section Building a Shared Library, for information on how to build shared libraries using Libtool and the `LTLIBRARIES' primary.
Each `_LIBRARIES' variable is a list of the libraries to be built. For instance to create a library named `libcpio.a', but not install it, you would write:
noinst_LIBRARIES = libcpio.a
The sources that go into a library are determined exactly as they are for programs, via the `_SOURCES' variables. Note that the library name is canonicalized (see section How derived variables are named), so the `_SOURCES' variable corresponding to `liblob.a' is `liblob_a_SOURCES', not `liblob.a_SOURCES'.
Extra objects can be added to a library using the
`library_LIBADD' variable. This should be used for objects
determined by configure
. Again from cpio
:
libcpio_a_LIBADD = @LIBOBJS@ @ALLOCA@
In addition, sources for extra objects that will not exist until
configure-time must be added to the BUILT_SOURCES
variable
(see section Built sources).
